The power button lights up when power is on, but won't turn on. Had problems with volume changing on it's own and turned it off, now it won't turn on.

1. Hold [menu] and [vol-] button on the side of the TV
2. while holding these, press the [power] button on the side of TV (NOT remote)
3. blue light comes ON and stays ON
4. wait 10 seconds then let go of [menu] and [vol-]
5. wait another 30 seconds and some type of picture should appear

I think this is right. I got it from the JVC call centers guys so sorry if I missed or messed up a step.

SOURCE: on button keeps clicking on and off, unit

I would certainly find a bad capacitor in the standby(deflection area). You are not getting the correct voltage to keep this set in standby. A bad capacitor will over correct the voltage,and create a high voltage shut down. I have not repaired this particular model. I would look for a 160 to 250 volt capacitor (sometimes two) at 1 Mf, 2.2, 3.3 or 4.7Mf. These will always go down. Please inspect check and replace these. Your TV may come back on. If it will not power up, chances you have a bad picture tube.A bad picture tube will also do as you describe (Rare,but can happen). Thanks for asking and show all hands of support!

Power button won't turn radio off


I've got the same problem. All other functionality is fine, however I can't turn the unit off once I've turned it on. I can use the power button to adjust volume, just not turn it off, so I have to unplug it to get it to turn off.

My sony bravia klv40ex600 won't turn on,the light indicator for power,volume and channel is on, the screen is still black


Hi, have you tried pressing the TV button that is under the On/Off button on top right hand side of remote control? Some times its possible to accidently press the DVD or VCR controls and this by-passes the TV as a remote?
Another cause can be a poor or low battery in the remote itself. If you have no luck let me know & we can try some more things, however, I have heard that The On/Off Switch on the TV can be a problem. Goodluck, Jon..

Assuming your deck is a kdc 516s the flexible cable that goes from the face to the main motherboard is probably bad. If you are not good at desoldering and soldering. , I would suggest you have it replaced by a professional.

Hi.

Take out the AC power jack and then remove the laptop battery. Plug AC power back in and see if the laptop will turn on. If it turns on let it boot the operating system and then shut down as normal, remove the power cord and reinsert the battery and again see if it will switch on. If it does then there has been a glitch with the battery. If it doesn't then there is a problem with the battery.

If the laptop won't switch on either with or without the battery then there is a possibility that the motherboard has developed a problem.


Good luck.

Power button failure


  • Power Light Shuts Off
    If the power shuts off during game play (even as much as 30 minutes after the system is turned on), then turns off and won't turn back on or the fan isn't working, the system needs repair.
  • Power Light Flashes
    If the power light flashes once when power button is pressed, then turns off and won't turn back on, the system needs repair
